The Siemens 3RF3350-3AA24 is a 1-pole SIRIUS 3RF33 solid-state contactor rated for 50 A in AC-1 duty at 40 °C, with a control supply of 110-230 V AC and a main circuit voltage range of 48-460 V. The AC-1 rating covers resistive or lightly inductive loads — heaters, lighting banks, transformer primaries — not motor starts. The ring cable lug connection means you torque a lug onto the terminal stud rather than stuffing a wire into a cage; it wires up clean if your panel uses ring terminals, but it takes a bit more planning on the wireway than a push-in clamp.
